I am trying to rewrite my website in Rails 3 and Ruby 1.9.2. Can some one help me convert my observe_field which is working under Rails 2.3.5 to Rails 3. I would like to avoid using JQuery as over the last year everything I have tried in JQuery has failed, including this one. Perhaps due to my lack of knowledge. I would not like to install the legacy upgrade. What I have in my website is several

Hey. Below is a patch to allow generic Ajax.Autocompleters. Basically it''s for people who wanna be able to watch an input for changes, but don''t want it to pop up an autocompleter box below.

Hi I''ve just started experimenting with AJAX in Rails and have come across this issue. I''m trying to set up some ajax form validation on a login form. I set up an observe_field method for the username field but the action for the containing form is being called and rendered instead of the action I specify in the observe_field method. All of the observe_field examples

I''m sure this is a simple problem, but I''ve been working on it for a couple days and can''t seem to figure out the correct way to structure my observe_field call. The HTML and Javascript generated all appear correct, but the AJAX call is never made. Below is the code I''m using and any help would be much appreciated. models_controller.rb def

Hi, I''ve got a live_search field in a partial that is on several different pages. On all pages, except 1, it works fine. On the page it doesn''t work on, it seems it never executes it action.

Hi, I need to observe a set of radio buttons but am having great trouble. My observe_field looks like this: <%= observe_field :user_select, :frequency => 0, :url => { :action => :admin_control } %> Now it works fine if I use a text_field like this: <%= text_field :user, :select, "size" => 20, "maxlength" => 16 %> But I want a radio button, and

I have a page that has a dropdown which i''m using observe_field on to make an ajax call back to my controller. The page initially displays fine.
